To all whom it may concern:

Be it known that 1, Artemis i on rnn, a citizen of the United States, reading at.

Berkeley, in the county of Alfiineda and State of California, have invented certain new and useful Improvements in Centrifugal Machines for Purifying Liquids, of which the following a specification.

The hereinafter ribed invention reletes to the purifying or" liquids generally, although more particularly designed for the treatment of water for the manufacture of ice; the object of the inventi m being to purify the li eds without changing the chemical eozn ion thereof by oxygenetion, by contact wlth the atmosphere, and to this end it cor lists in subjecting the liquid to be treated U) centrifugal action within a liquid sealed apparatus revolved at a high rate of velocity, whereby the solid impurr ties, held insuspension in the liquid, are thrown, by the centrifugal force generated by the motion of the apparatus, outwardly and lodged against the wall of the revolving bowl containing the liquid under treatment, and the impure aeriform "fluids forced toward the center of the said bowl and ere elled therefrom through a vent provided or that urpose; the purified liquid dis charging rem the revolving bowl oi the rep paratus through a submerged outlet, end, by such submerged outlet, the purified liquid being discharged without being brought into contact with the outside etmospaere, thus avoidin the do rirneut oi" oxygenation which otherwise uld tulre place.

To comprehend the tion. reference ny'ing sheet should be head to the scco drawings, wherein Figure l is an sectional view of the a ipsrstus token on line 1 -13 Fig 3 of the drawings, F is e detail plan view oi? the accelerator removed from the bowl which receives the liquid to be treated. Fig. is a cross sectional plan view taken on line A A of l of the drawings. Fi is similar view tslreu on line C-C of ig. l of the drawings.

In the drawn s, the numeral 1 is used to indicate uitz h bowl for the reception of the lie, to treated, which bowl is at tached to s suspended drive shaft 2, driven by a belt or other suitable means, end through drive shaft, within the bowl 1, is formed etan upward inclination e gas outlet vent 2-", The bowl 1 is provided with a removable cover 3, in which is fitted en acceleretor 4,, provided with e series of radial inlet passages 4. This accelerator can ries e downwar ly projecting hollow conical extension 5, which, at its lower end portion, is provided with a vent opening 5, through which the gases are admitted into the interior of the said hollow conical extension- During the operation of the apparatus, when the bowl 1 is substantially filled with the liq uid to be treated, there is formed below the conical extension 5, and inside of the dotted line m, Fig. l of the drawings, an annular space or channel 5 as hereinafter explained. I \Vithin the bowl l and near the bottom. thereof, is attached a oi'oss'piie'cefi, which carries and supports a div '7', which, at its outer edge portion is out out to provide the passages 8 for the escape of the purified liquid, which purified liquid discharges from the bowl 1 through said passages or discharge openings into 2t downwardly projecting tubular i extension 9 of the said bowl 1. This tubular extensiorl is provided with e central core-piece it), which depends from the cross pieces '5, end forms within the extension 9 an annular discharge passage 11, of e conveying capaci ivequul to the working capacity of the apps rates. At its lower end, the central core piece 10 is held in position by means of the sp'acing lugs 12.

The fluid orgliquid to be treated is contained preferably in a supply tank or reservoir 13, located at any suitable point, which tank or reservoir is connected by the feed pipe or conduit 14: with an aiuiuler inlet 15,

which delivers the liquid through the cover 3 to the accelerator d, the liquid so delivered passing into the bowl 1 through the vertical radial inlets or passages of the accel orator. If the feed or supply of liquid to be treated is greater than the outlet area of discharge the bowl 1 will become filled to over-- flowing and to avoid such overcrowding of the said how l it is neoessar supply of the liquid be a justed in sc'c'ordence with its capacity of discharge into the tubular extension 9. To tithe care of such overflow of the liquid he may occur prior to the supplv b rig 'oroperly adjusted, there is vcymg rwerliow to it suitable place of deposit.

The tubular extension 9 extends within or ding plate or disk that the feed or receiver 19 for the purified liquid, which dischar es from the bottom thereof through the out et pipe 20. The receiver 19 into which thee-tubular extension 9 projects is filled with liquid, so that the outflow from said extension will be a submerged one and out of contact with the outside atmosphere.

The intention is, as hereinafter explained,

that the receiver 19 shall be filled to overflowing and, throughoutthe Working or treatment. of the liquid, a constant overflow maintained from the receiver 19, such overflow entering the annular trough 21, from whence 1t escapes through the outlet 22. i

To prevent nand circulation of the purified liquid Within the receiver 19 as delivered thereto from the revolving bowl 1, a series of vertical and radiallu extended -Wing's or" blades 23 are provided, which wings or blades bring the liquid delivered into the stationary receiver 1-9 to state of rest v I in order to expel all air contained int ie pipe 20 at the startin up oi the ap aratus tor the Work of puri ingliquids, c said pipe is provided with an air ventflfi. The said pipe 20 is also pro'videdan outlet regulating cock 26, the purposepf which is that the overflow of the purified liquid from within the receiver 19 may be gaged or regulated, so that a small fraction thereof will continually overflow the top of the receiver into the trough 21. It will be understood that the pipe'QO conveys the purified liquid to the respective point of discharge,

which may be located at any point'beyond the receiver 19. I

The operation of purifying the liquid is follows: The liquidtc be treated is supplied from the reservoir 13 to the annular inlet 15, which. delivers the liquid into the upper extension of the cover 3 of the rapidly resolving bowl 1, where .it is caught AR Ll'lB ve ccit continuing its down Ferd travel on line near to and parallel with the outer of the bowl, withoutfniir ng with the of the liquid forming the inner of the contents acting as seal the central port-ion of the bowl. The f" d thus VMA ' entering the bowl 1 is subjected to the r-harriiouincentriiugal force generated in t le apuuder tlie'infiuencc of which the Elli-1.

parses, i 1 1 no" oluble Impurities are separated lo 1e wall oi the M specific gravity, are forced to seek the cen tral space or chamber 6 inside the dot-ted line m, which represents the extreme inner surface of the liquid under treatment, from whence they escape through the vent opening into the interior of the conical extension 5, being discharged from the interior of the said extension through the outlet vent opening or bore 2' in the drive shaft 2, Fig. 1 of the drawings, The purified liquid leaves the separating chamber or interior of the bowl 1 through the series of outlets or or disk 7, continues its course downwardly through the annular passage 11 of the tubuefxten'sion 9, until finally discharged at .tlldx'i-rlhe lower; end of the said passage and delivered into and near the bottom of the receiver 19, which during the entire treatment of the liquid is kept filled to overflowing, by gaging the discharge of the puritied liquid through the outlet pipe by means of the regulating cook 26. The puritied liquid being discharged from the tubular extension 9 through a submerged outlet, is prevented from coming into contact with the outside atmosphere.

When theapparatus is used for purifying milk, or other compound liquids of different specific gravity, from which the cream, or lighter component in such liquid will partly separate and collect along 'thd' viding plate 7! is dispensed with, in order to allow or leave an unobstructed passage for the separated lighter component and permit the same to'xsove downward and remix with the rest of the treated liquid just prior being disc iarged from the apparatus.
